title: Metastatic placental site trophoblastic tumor: long-term remission in a patient treated with EMA/CO chemotherapy.
abstract: OBJECTIVE
  We document a case of long-term remission in a patient with metastatic placental site trophoblastic tumor (PSTT) and attempt to determine the response rate of metastatic PSTT to EMA/CO (etoposide, methotrexate, actinomycin-D, cyclophosphamide, and vincristine) combination chemotherapy based on available reports.
  
  
  METHODS
  Medical records, histological slides, and radiological films were reviewed for a patient with metastatic PSTT diagnosed in 1991. Using Medline and cross-references, pertinent articles were reviewed.
  
  
  RESULTS
  A 31-year-old patient with PSTT metastatic to the lungs and vagina is presently alive, without evidence of recurrent cancer, more than 6 years after treatment with EMA/CO chemotherapy and surgery. The total response rate for seven patients with metastatic PSTT treated with EMA/CO chemotherapy was 71% with a complete response rate of 28%.
  
  
  CONCLUSIONS
  Metastatic PSTT is potentially curable. EMA/CO chemotherapy appears superior to older multiagent regimens used in treating PSTT.
